In a method for coating on a surface of a medical PEEK material with titanium to have a microporous structure, titanium is coated on a surface of polyether ether ketone (PEEK) via magnetron sputtering. The surface of the titanium coated on the surface of PEEK is polished via an electromagnetic polishing apparatus. A thin-film with titanium dioxide (TiO.sub.2) having a microporous structure is formed on the polished surface of the titanium via an anodic oxidation treatment.

A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).

A system for magnetic abrasive finishing of a workpiece may include a magnetic abrasive brush that may include a plurality of magnetic/abrasive particles and an electromagnet configured to apply a magnetic field on the plurality of magnetic abrasive particles. The system may further include a first actuating mechanism that may be configured to actuate a rotational movement of the workpiece about a longitudinal axis of the workpiece, a second actuating mechanism that may be configured to actuate a linear movement of the magnetic abrasive brush along a first direction relative to the workpiece, the first direction parallel to the longitudinal axis of the workpiece, a sensor coupled to the magnetic abrasive brush that may be configured to measure a working gap between the magnetic abrasive brush and an outer surface of the workpiece at any given instant. The working gap may be a distance between a center of the magnetic field and the outer surface of the workpiece along a first axis perpendicular to the longitudinal axis of the workpiece. The system may further include a control unit that may be coupled to the magnetic abrasive brush and may be configured to adjust a magnetic flux density of the magnetic field based on the measured working gap at any given instant.
